Abstract
Abstract A fluid delivery system has a container with an integrally attached sample cell. A selected fluid can be accumulated in the container. The sample cell can be filled with part of the fluid in the container and then isolated from the container by heat or dielectric sealing. The fluid in the sample cell can be brought into contact with selected test reagents. The test reagents can provide a visual indicia of the presence of selected characteristics in the fluid.
